cmGlobalGenerator: Initialize generator targets on construction (#15729) The Ninja generator and Visual Studio generators are special-cased for the QtAutogen feature. In order to reduce the number of custom targets, the Visual Studio generators prefer to create custom commands instead, and in order to create appropriate Ninja files, generated rcc files are listed as byproducts. This requires the use of the GetConfigCommonSourceFiles API of the cmGeneratorTarget for those generators when initializing the autogen target. The initializer method is called from Compute() after the cmGeneratorTarget objects are created, however the initialization of the object directory occurs later in the InitGeneratorTargets method. That means that the resulting object locations are computed incorrectly and cached before the object directory is determined, so the generated buildsystem can not find the object files. The initialization of the object directory was split from the creation of cmGeneratorTarget instances in commit 0e0258c8 (cmGlobalGenerator: Split creation of generator object from initialization., 2015-07-25). The motivation for the split was to do only what is essential to do early in cases where cmGeneratorTargets need to be created at configure-time. That is required for the purpose of implementing policies CMP0024 and CMP0026, and for try_compile(LINK_LIBRARIES). However, the split was not really necessary. Compute the object directory in the cmGeneratorTarget constructor instead. The QtAutogen unit test already tests the use of TARGET_OBJECTS with AUTOMOC, and that test already passes on Ninja. The reason it already passes is that the QtAutogen target also uses the AUTORCC feature, and specifies several qrc files in its SOURCES. Later in the Compute algorithm (after the InitGeneratorTargets call), the rcc files are determined and target->AddSource is called. The AddSource call clears the previously mentioned cache of source files, causing it to be regenerated when next queried, this time taking account of the object directory. Extend the test suite with a new target which does not make use of AUTORCC with qrc files so that the test added alone would break without the fix in this commit.
